The verses of Al-Quran were handed down with Arabic vocabularies. Except some words that were included in its vocabularies that was caused by the acculturation. Al-Quran claimed this matter. There are some factors that caused the Arabic language was chosen to be Al-Quran language. They are: First, the characteristic of Arabic language. Arabic language in Al-Quran has a poetic characteristic because commonly the Arabic Society at that time were poets or men of letters. Arabic language in Al-Quran was included in the family language of Smith, as well as Hebrew, Aramaik, Suryani, Kaldea, and Babylonia languages. Commonly, the word of Arabic language have three consonants as their basic that can be formed into so many forms. For instance, the word "qaala" means "say" was formed from qaaf, alif, and lam letters. Utsman Bin Jinni, an Arabic Linguist emphasized that the choosing of letters in Arabic vocabularies are not by chance, but they contained their own philosophy of language. Arabic language is rich from its vocabularies, that can be seen in the numeral, (mufrad)/ singular, mutsanna/ more than but les than three, and jamaa/ more than two/ plural), the gender (man and woman) and also in muradif (synonim) and antonym. Second, Arabic language as divine revelations. The second reason that caused the Arabic language as Gods divine revelations was because it was interrelated with those dissemination factors. Beside using the Mubasyaroh method, studying the Arabic language needs the Qawa'id (principles) method too, the basic of word "qawa'id" is "aqidah" means building, rule, regulation, or principle. Actually, the totality of Qawa'id essence is Nahwu and Syaraf. Qawa'id material is, a grammar of Arabic language that is holistic and comprehensive, so from it, the set of problems in Arabic language either from a word form and its existence when it stands by itself, or the arrangement of sentences that consist from the combination of fi'il (verb), isim (noun) and letter.
